Description

本発明は、アンテナ装置に関するものである。 The present invention relates to an antenna device.

公知のアンテナ装置として、後述の特許文献１に記載のものがある。このアンテナ装置について、図１１を参照して説明する。 As a known antenna device, there is one described in Patent Document 1 described later. This antenna device will be described with reference to FIG.

アンテナ装置１は、車両のドアミラーに設けられている。アンテナ装置１は、ドアミラーのベース部材２の背面側（図１１中矢示参照）に取り付けられている。さらに、ベース部材２の背面側には、アンテナ装置１を挟みこむように、ハウジング３が取り付けられている。ベース部材の手前側（図１１中矢示参照）には、ミラー（図示なし）が設けられる。 The antenna device 1 is provided on a door mirror of a vehicle. The antenna device 1 is attached to the back side of the base member 2 of the door mirror (see the arrow in FIG. 11). Furthermore, a housing 3 is attached to the back side of the base member 2 so as to sandwich the antenna device 1. A mirror (not shown) is provided on the front side of the base member (see arrow in FIG. 11).

アンテナ装置１は、２つのループアンテナ４，５を備えている。ループアンテナ４は、磁心４ａに導線が巻回されて成り、ループアンテナ５におけるループ面の中心に配置されている。ループアンテナ４の磁心４ａには、制御装置（図示なし）に接続される２本の信号線４ｂが、導線とともに巻回されている。
特公平６−３８５６２号公報（第１図参照） The antenna device 1 includes two loop antennas 4 and 5. The loop antenna 4 is formed by winding a conductive wire around a magnetic core 4 a and is arranged at the center of the loop surface of the loop antenna 5. Two signal wires 4b connected to a control device (not shown) are wound around a magnetic core 4a of the loop antenna 4 together with a conducting wire.
Japanese Patent Publication No. 6-38562 (see FIG. 1)

ところで、上述のアンテナ装置１においては、２本の信号線４ｂの両方が、ループアンテナ４の磁心４ａにおける室内側（図１１中矢示参照）から外部に導出されている。つまり、磁心４ａに対する信号線４ｂの巻き始め側と巻き終わり側の両方が、磁心４ａの室内側から外部に導出されている。 By the way, in the above-described antenna device 1, both of the two signal lines 4 b are led out to the outside from the indoor side (see arrow in FIG. 11) in the magnetic core 4 a of the loop antenna 4. That is, both the winding start side and winding end side of the signal line 4b with respect to the magnetic core 4a are led out from the indoor side of the magnetic core 4a.

この構造においては、仮に、信号線４ａに接続される制御装置（接続対象物）に対してアンテナ装置１が室内側に設置される場合には、アンテナ装置１が室外側（図１１中矢示参照）に配置される場合に比べて、アンテナ装置１と制御装置とを接続する信号線４ｂの配策構造が大きく異なったものとなる。例えば、磁心４ａの室内側から導出された信号線４ｂを磁心４ａ（アンテナ装置１）の室外側へと配策することになるので、信号線４ｂの長さが余分に必要となる。また、信号線４ｂを屈曲させる箇所が増えることにより、信号線４ｂの配策構造が複雑化する可能性がある。 In this structure, if the antenna device 1 is installed indoors with respect to the control device (object to be connected) connected to the signal line 4a, the antenna device 1 is outside the room (see the arrow in FIG. 11). The arrangement structure of the signal line 4b that connects the antenna device 1 and the control device is significantly different from the case where the antenna device 1 and the control device are arranged. For example, since the signal line 4b derived from the indoor side of the magnetic core 4a is routed to the outdoor side of the magnetic core 4a (antenna device 1), an extra length of the signal line 4b is required. In addition, an increase in the number of places where the signal line 4b is bent may complicate the routing structure of the signal line 4b.

このように、アンテナ装置１を設置する場合、自身に信号線を介して接続される接続対象物との位置関係によっては不都合が生じることとなり、その設置に係る汎用性の観点から考えると、改善の余地があった。 As described above, when the antenna device 1 is installed, an inconvenience arises depending on the positional relationship with the connection target connected to the antenna device 1 via the signal line, which is improved from the viewpoint of versatility related to the installation. There was room for.

以下、本発明を実施するための最良の形態を、図面を基に説明する。 The best mode for carrying out the present invention will be described below with reference to the drawings.

図１は、本発明に係るラゲージアンテナ１０（アンテナ装置）の外観構造を示す図である。図２は、図１におけるＩＩ−ＩＩ線に沿う断面図である。 FIG. 1 is a diagram showing an external structure of a luggage antenna 10 (antenna device) according to the present invention. 2 is a cross-sectional view taken along line II-II in FIG.

ラゲージアンテナ１０は、スマートエントリーシステムを構築する一部品で、車両のバンパーカバー内のボディパネル９に取り付けられている。ラゲージアンテナ１０は、車両に設けられるトランクリッド（図示なし）を、メカニカルキー操作や既存のリモコンキーのボタン操作を行うことなく施解錠するためのものである。 The luggage antenna 10 is one component for constructing a smart entry system, and is attached to the body panel 9 in the bumper cover of the vehicle. The luggage antenna 10 is for locking and unlocking a trunk lid (not shown) provided in the vehicle without performing mechanical key operations or button operations of existing remote control keys.

トランクリッドが施錠されている状態で、携帯機を持ったユーザが、トランクリッド近傍に設けられたスイッチ（図示なし）を押すと、ラゲッジアンテナ１０を介して、車両から携帯機に電波が発信される。これを受けて、携帯機と車両との間でＩＤコードが照合され、これらＩＤコードが一致した場合には、トランクリッドが解錠される構造となっている。 When a user with a portable device presses a switch (not shown) provided near the trunk lid while the trunk lid is locked, a radio wave is transmitted from the vehicle to the portable device via the luggage antenna 10. The In response, the ID code is collated between the portable device and the vehicle, and when these ID codes match, the trunk lid is unlocked.

ラゲージアンテナ１０は、磁心１１と、被覆電線１２と、ケース１３と、カバー１４とを備えている。 The luggage antenna 10 includes a magnetic core 11, a covered electric wire 12, a case 13, and a cover 14.

磁心１１には、被覆電線１２が巻回されている。被覆電線１２の巻き始め側１２ａ及び巻き終わり側１２ｂは、磁心１１から導出されている。磁心１１から導出された被覆電線１２の巻き始め側１２ａ及び巻き終わり側１２ｂは、導出部１２ｃを成している。ケース１３は、被覆電線１２が巻回された磁心１１を収容している。ケース１３には、カバー１４が嵌合されている。被覆電線１２の導出部１２ｃは、ケース１３の内部を経由して、ケース１３の外部に導出されている。被覆電線１２の導出部１２ｃの端末１２ｄには、コネクタ１２ｅが取り付けられている。コネクタ１２ｅは、トランクリッドの施解錠を司る制御装置（図示なし、対象物）に接続される。以下、これら磁心１１、被覆電線１２、ケース１３、及びカバー１４の詳しい構造について、図３乃至図９を参照して説明する。 A covered electric wire 12 is wound around the magnetic core 11. The winding start side 12 a and the winding end side 12 b of the covered electric wire 12 are led out from the magnetic core 11. The winding start side 12a and the winding end side 12b of the covered wire 12 led out from the magnetic core 11 form a lead-out part 12c. The case 13 accommodates the magnetic core 11 around which the covered electric wire 12 is wound. A cover 14 is fitted to the case 13. The lead-out part 12 c of the covered wire 12 is led out of the case 13 via the inside of the case 13. A connector 12e is attached to the terminal 12d of the lead-out portion 12c of the covered electric wire 12. The connector 12e is connected to a control device (not shown, object) that controls locking and unlocking of the trunk lid. Hereinafter, detailed structures of the magnetic core 11, the covered electric wire 12, the case 13, and the cover 14 will be described with reference to FIGS.

図３は、磁心１１の構造を示す上面図、図４は、被覆電線１２が巻回された磁心１１の構造を示す上面図、図５は、被覆電線１２が巻回された磁心１１の構造を示す正面図（図４におけるＶ方向矢視図）である。 3 is a top view showing the structure of the magnetic core 11, FIG. 4 is a top view showing the structure of the magnetic core 11 around which the covered electric wire 12 is wound, and FIG. 5 is a structure of the magnetic core 11 around which the covered electric wire 12 is wound. It is a front view (V direction arrow line view in FIG. 4) which shows.

磁心１１は、リボン１１ａ（磁性体）と、ボビン１１ｂ（保持体）とを備えている。リボン１１ａは、ボビン１１ｂに巻回されている。 The magnetic core 11 includes a ribbon 11a (magnetic body) and a bobbin 11b (holding body). The ribbon 11a is wound around the bobbin 11b.

リボン１１ａは、薄帯状のアモルファス合金から成る。リボン１１ａの材質は、薄帯状のアモルファス合金に限定されず、薄帯状の磁性材料であれば良い。ボビン１１ｂ（保持体）は、ガラス繊維強化の樹脂材料（例えば、ＰＰＳ、液晶ポリマー樹脂）からなり、リボン１１ａを保持している。ボビン１１ｂの材質は、絶縁体であれば良いが、ある程度の強度及び柔軟性を有する樹脂材料を用いることが好ましい。 The ribbon 11a is made of a ribbon-like amorphous alloy. The material of the ribbon 11a is not limited to a ribbon-like amorphous alloy, and any ribbon-like magnetic material may be used. The bobbin 11b (holding body) is made of a glass fiber reinforced resin material (for example, PPS, liquid crystal polymer resin), and holds the ribbon 11a. The material of the bobbin 11b may be an insulator, but it is preferable to use a resin material having a certain degree of strength and flexibility.

ボビン１１ｂは、大まかには、細長の薄板形状を呈している。ボビン１１ｂにおいて、その長手方向（図３示左右方向）の一方側１１ｃ及び他方側１１ｄには、係止部１１ｅ，１１ｆがそれぞれ一体に設けられている。係止部１１ｅ，１１ｆは、ボビン１１ｂの厚み方向（図３於紙面直交方向）に延在する爪状を呈している。ボビン１１ｂにて、その長手方向の略中央部１１ｋには、結束部１１ｇ，１１ｈが一体に設けられている。結束部１１ｇ，１１ｈは、係止部１１ｅ，１１ｆと同様に、ボビン１１ｂの厚み方向（図３於紙面直交方向）に延在する爪状を呈している。 The bobbin 11b is roughly in the form of an elongated thin plate. In the bobbin 11b, locking portions 11e and 11f are integrally provided on one side 11c and the other side 11d in the longitudinal direction (left and right direction in FIG. 3), respectively. The locking portions 11e and 11f have a claw shape extending in the thickness direction of the bobbin 11b (the direction perpendicular to the paper surface in FIG. 3). In the bobbin 11b, bundling portions 11g and 11h are integrally provided at a substantially central portion 11k in the longitudinal direction. The bundling portions 11g and 11h have a claw-like shape extending in the thickness direction of the bobbin 11b (the direction orthogonal to the paper surface in FIG. 3), like the locking portions 11e and 11f.

被覆電線１２は、銅線をより合わせた心線と、この心線を同軸に被覆する絶縁体の被覆材とで形成された汎用のものである。 The covered electric wire 12 is a general-purpose one formed of a core wire obtained by twisting copper wires and an insulating covering material that covers the core wire coaxially.

図４及び図５に示す様に、被覆電線１２は、ボビン１１ｂに対し、一方側１１ｃから巻き始められると共に他方側１１ｄにて巻き終わる。被覆電線１２の巻き始め側１２ａ及び巻き終わり側１２ｂは、ボビン１１ｂに予め一体に設けられた係止部１１ｅ，１１ｆにより、ボビン１１ｂに対してそれぞれ係止される。この場合、被覆電線１２の巻き始め側１２ａ及び巻き終わり側１２ｂは、爪状の係止部１１ｅ，１１ｆに引っ掛けられることで、ボビン１１ｂに対して係止される。 As shown in FIGS. 4 and 5, the covered electric wire 12 starts to be wound around the bobbin 11b from the one side 11c and finishes winding at the other side 11d. The winding start side 12a and the winding end side 12b of the covered electric wire 12 are locked to the bobbin 11b by locking portions 11e and 11f provided integrally with the bobbin 11b in advance. In this case, the winding start side 12a and the winding end side 12b of the covered electric wire 12 are locked to the bobbin 11b by being hooked by the claw-shaped locking portions 11e and 11f.

ボビン１１ｂに対して係止された被覆電線１２の巻き始め側１２ａ及び巻き終わり側１２ｂの残り、すなわち被覆電線１２の導出部１２ｃは、ボビン１１ｂに予め一体に設けられた結束部１１ｇ，１１ｈにより、ボビン１１ｂの長手方向の略中央部１１ｋにて束ねられる。この場合、被覆電線１２の導出部１２ｃは、爪状の結束部１１ｇ，１１ｈに引っ掛けられることで束ねられる。束ねられた被覆電線１２の導出部１２ｃの端末１２ｄには、コネクタ１２ｅが設けられている。コネクタ１２ｅは、上述した制御装置に接続される。 The remainder of the winding start side 12a and the winding end side 12b of the covered electric wire 12 locked to the bobbin 11b, that is, the lead-out portion 12c of the covered electric wire 12 is formed by bundling portions 11g and 11h provided integrally with the bobbin 11b in advance. The bobbin 11b is bundled at a substantially central portion 11k in the longitudinal direction. In this case, the lead-out portion 12c of the covered electric wire 12 is bundled by being hooked on the claw-like binding portions 11g and 11h. A connector 12e is provided at the terminal 12d of the lead-out portion 12c of the bundled covered electric wire 12. The connector 12e is connected to the control device described above.

本実施形態において、被覆電線１２の導出部１２ｃを束ねる結束部１１ｇ，１１ｈは、ボビン１１ｂの長手方向の略中央部１１ｋに設けられている。したがって、被覆電線１２にコネクタ１２ｅを介して接続される制御装置が、ラゲージアンテナ１０における磁心１１の一方側１１ｃに近い位置及び他方側１１ｄに近い位置のいずれに設置される場合であっても、磁心１１と制御装置との間において、被覆電線１２の導出部１２ｃの配策には、不都合が生じない。その結果、磁心１１から導出された被覆電線１２の導出部１２ｃを、コネクタ１２ｅを介して、制御装置に好適に接続できる。 In the present embodiment, the bundling portions 11g and 11h for bundling the lead-out portion 12c of the covered electric wire 12 are provided at a substantially central portion 11k in the longitudinal direction of the bobbin 11b. Therefore, even if the control device connected to the covered wire 12 via the connector 12e is installed at either the position near the one side 11c of the magnetic core 11 or the position near the other side 11d in the luggage antenna 10, There is no inconvenience in the arrangement of the lead-out portion 12c of the covered electric wire 12 between the magnetic core 11 and the control device. As a result, the lead-out portion 12c of the covered wire 12 led out from the magnetic core 11 can be suitably connected to the control device via the connector 12e.

図６は、ケース１３の構造を示す上面図、図７は、ケース１３の構造を示す正面図（図６におけるＶＩＩ方向矢視図）である。なお、図７においては、部分的に断面が描かれている。 6 is a top view showing the structure of the case 13, and FIG. 7 is a front view showing the structure of the case 13 (viewed in the direction of arrow VII in FIG. 6). In FIG. 7, a cross section is partially drawn.

ケース１３は、樹脂材料からなり、大まかには、細長の箱状を呈している。ケース１３は、保持部１３ａと、通路１３ｂとを備えている。 The case 13 is made of a resin material and has a roughly elongated box shape. The case 13 includes a holding portion 13a and a passage 13b.

保持部１３ａは、ケース１３の長手方向（図６及び図７示左右方向）に延在し、ケース１３の厚み方向（図７示上下方向）に関して凹状を成している。保持部１３ａは、被覆電線１２が巻回された磁心１１（図４及び図５参照）を保持する。保持部１３ａの幅方向（図６示上下方向）の寸法は、被覆電線１２が巻回された磁心１１の厚み方向（図５示上下方向）の寸法に対応して設定されている。被覆電線１２が巻回された磁心１１は、そのボビン１１ｂがケース１３の保持部１３ａに圧入されることで、ケース１３に対して保持される構造となっている。 The holding portion 13a extends in the longitudinal direction of the case 13 (the left-right direction shown in FIGS. 6 and 7), and has a concave shape in the thickness direction of the case 13 (the up-down direction shown in FIG. 7). The holding portion 13a holds the magnetic core 11 (see FIGS. 4 and 5) around which the covered electric wire 12 is wound. The dimension of the holding part 13a in the width direction (up and down direction in FIG. 6) is set corresponding to the dimension in the thickness direction (up and down direction in FIG. 5) of the magnetic core 11 around which the covered electric wire 12 is wound. The magnetic core 11 around which the covered electric wire 12 is wound has a structure in which the bobbin 11 b is held against the case 13 by being press-fitted into the holding portion 13 a of the case 13.

通路１３ｂは、大まかにはケース１３の長手方向に延在し、ケース１３の厚み方向に関して凹状を成している。通路１３ｂには、磁心１１から導出された被覆電線１２の導出部１２ｃが挿通される。通路１３ｂには、凹部１３ｃが設けられている。凹部１３ｃは、通路１３ｂにおいて、ケース１３の長手方向の各側に２箇所ずつ、計４箇所に設けられている（図７においては２箇所にのみ符番を付す）。凹部１３ｃは、ケース１３の厚み方向に関して凹状を成している。凹部１３ｃは、通路１３ｂの延在する方向に沿って設けられている。 The passage 13b extends roughly in the longitudinal direction of the case 13 and is concave in the thickness direction of the case 13. The lead-out portion 12c of the covered electric wire 12 led out from the magnetic core 11 is inserted into the passage 13b. A recess 13c is provided in the passage 13b. The recess 13c is provided at a total of four locations, two on each side in the longitudinal direction of the case 13 in the passage 13b (in FIG. 7, only two locations are numbered).

図８は、カバー１４の構造を示す上面図、図９は、図８におけるＩＸ−ＩＸ線に沿う断面図である。 8 is a top view showing the structure of the cover 14, and FIG. 9 is a cross-sectional view taken along the line IX-IX in FIG.

カバー１４は、樹脂材料からなり、大まかには、細長の板状を呈している。カバー１４は、ベース１４ａと、凸部１４ｂと、嵌合部１４ｃとを備えている。 The cover 14 is made of a resin material, and roughly has an elongated plate shape. The cover 14 includes a base 14a, a convex portion 14b, and a fitting portion 14c.

ベース１４ａは、板状を呈し、カバー１４の構造における基部として機能する。 The base 14 a has a plate shape and functions as a base in the structure of the cover 14.

凸部１４ｂは、ベース１４ａにおいて、カバー１４の長手方向（図８及び図９示左右方向）の各側に２箇所ずつ、計４箇所に設けられている。凸部１４ｂは、カバー１４の厚み方向（図９示上下方向）に関して凸状を成している。 The convex portions 14b are provided at four locations, two on each side of the base 14a in the longitudinal direction of the cover 14 (the horizontal direction in FIGS. 8 and 9). The convex portion 14b has a convex shape in the thickness direction of the cover 14 (the vertical direction in FIG. 9).

嵌合部１４ｃは、ベース１４ａにおいて、長手方向の両側に設けられている。嵌合部１４ｃは、カバー１４の厚み方向に関してベース１４ａから延在している。 The fitting portions 14c are provided on both sides in the longitudinal direction of the base 14a. The fitting portion 14 c extends from the base 14 a in the thickness direction of the cover 14.

カバー１４は、磁心１１を保持したケース１３に対し、この磁心１１を覆うように嵌合される。カバー１４がケース１３に嵌合された時には、カバー１４の凸部１４ｂが、ケース１３の凹部１３ｃに対向し、且つ係合するようになっている。なお、本実施形態においては、カバー１４に凸部１４ｂ、ケース１３に凹部１３ｃが設けられているが、これに限定されない。例えば、カバー１４に凹部、ケース１３に凸部が設けられ、これら凹部と凸部とが、カバー１４のケース１３への嵌合時に、互いに対向し、且つ係合する構造であっても良い。 The cover 14 is fitted to the case 13 holding the magnetic core 11 so as to cover the magnetic core 11. When the cover 14 is fitted into the case 13, the convex portion 14 b of the cover 14 faces and engages with the concave portion 13 c of the case 13. In this embodiment, the cover 14 is provided with the convex portion 14b and the case 13 is provided with the concave portion 13c. However, the present invention is not limited to this. For example, the cover 14 may be provided with a concave portion and the case 13 may be provided with a convex portion, and the concave portion and the convex portion may be opposed to each other and engaged when the cover 14 is fitted into the case 13.

以下、ラゲージアンテナ１０の組み立て作業について、図１０（ａ）〜（ｃ）を参照して説明する。図１０（ａ）〜（ｃ）は、カバー１４がケース１３に嵌合される時の態様を模式的に示す図である。 Hereinafter, the assembly operation of the luggage antenna 10 will be described with reference to FIGS. FIGS. 10A to 10C are diagrams schematically illustrating an aspect when the cover 14 is fitted into the case 13.

まず、図１０（ａ）に示す様に、被覆電線１２が巻回された磁心１１をケース１３の保持部１３ａに圧入すると共に、磁心１１から導出された被覆電線１２の導出部１２ｃをケース１３の通路１３ｂに挿通する。 First, as shown in FIG. 10A, the magnetic core 11 around which the covered electric wire 12 is wound is press-fitted into the holding portion 13 a of the case 13, and the lead-out portion 12 c of the covered electric wire 12 led out from the magnetic core 11 is used as the case 13. The passage 13b is inserted.

このとき、磁心１１から導出された被覆電線１２の導出部１２ｃは、図１０（ｂ）に示す様に、ケース１３の通路１３ｂに設けられた凹部１３ｃ上に配置され、まっすぐに伸びた状態となっている。 At this time, the lead-out portion 12c of the covered electric wire 12 led out from the magnetic core 11 is disposed on the concave portion 13c provided in the passage 13b of the case 13 as shown in FIG. It has become.

この状態で、ケース１３に対し、カバー１４を同図中の矢示Ａ方向に移動させると、図１０（ｃ）に示す様に、カバー１４がケース１３に嵌合され、ケース１３の通路１３ｂ内にて、カバー１４の凸部１４ｂとケース１３の凹部１３ｃとが互いに係合する。これにともなって、カバー１４の凸部１４ｂとケース１３の凹部１３ｃとの間に被覆電線１２の導出部１２ｃが挟み込まれ、これら部位の形状に沿って被覆電線１２の導出部１２ｃが折り曲げられる。なお、被覆電線１２の導出部１２ｃの端末１２ｄに取り付けられたコネクタ１２ｅは、カバー１４がケース１３に嵌合される時に、ケース１３の支持部１３ｄに取り付けられる。 In this state, when the cover 14 is moved with respect to the case 13 in the direction of arrow A in the figure, the cover 14 is fitted into the case 13 as shown in FIG. Inside, the convex part 14b of the cover 14 and the concave part 13c of the case 13 engage with each other. Accordingly, the lead-out portion 12c of the covered electric wire 12 is sandwiched between the convex portion 14b of the cover 14 and the concave portion 13c of the case 13, and the lead-out portion 12c of the covered electric wire 12 is bent along the shape of these portions. The connector 12e attached to the terminal 12d of the lead-out part 12c of the covered wire 12 is attached to the support part 13d of the case 13 when the cover 14 is fitted to the case 13.

被覆電線１２の導出部１２ｃのうち、ケース１３の通路１３ｂ内に配策される部分は、ケース１３の凹部１３ｃとカバー１４の凸部１４ｂとによって折り曲げられたことで、カバー１４がケース１３に嵌合される前に比べて、見かけ上長くなる。これにより、カバー１４がケース１３に嵌合された状態のラゲージアンテナ１０において、被覆電線１２の導出部１２ｃのうち、ケース１３の外部に露出する部分を短くできる。 Of the lead-out portion 12 c of the covered wire 12, the portion arranged in the passage 13 b of the case 13 is bent by the concave portion 13 c of the case 13 and the convex portion 14 b of the cover 14, so that the cover 14 is attached to the case 13. It is apparently longer than before being fitted. Thereby, in the luggage antenna 10 in a state where the cover 14 is fitted to the case 13, a portion of the lead-out portion 12 c of the covered wire 12 that is exposed to the outside of the case 13 can be shortened.

したがって、被覆電線１２の導出部１２ｃの長さを好適に設定しておくことで、ラゲージアンテナ１０においては、被覆電線１２の導出部１２ｃのうち、ケース１３の外部に露出する部分の長さを最小限のものとできる。その結果、ラゲージアンテナ１０の周囲にある部材との干渉から被覆電線１２の導出部１２ｃを保護するための部材（例えば、保護チューブ）が必要なく、ラゲージアンテナ１０における部品点数が低減される。 Therefore, by suitably setting the length of the lead-out portion 12c of the covered electric wire 12, in the luggage antenna 10, the length of the portion of the lead-out portion 12c of the covered electric wire 12 exposed to the outside of the case 13 is set. Can be minimal. As a result, there is no need for a member (for example, a protective tube) for protecting the lead-out portion 12c of the covered electric wire 12 from interference with members around the luggage antenna 10, and the number of parts in the luggage antenna 10 is reduced.

以上説明した様に、本発明のラゲージアンテナ１０によれば、被覆電線１２は、その巻き始め側１２ａ及び巻き終わり側１２ｂに所定の長さの導出部１２ｃを残して磁心１１に巻回され、導出部１２ｃは、磁心１１の長手方向の略中央部１２ｋにて束ねられる。束ねられた導出部１２ｃの端末１２ｄには、コネクタ１２ｅが設けられる。 As described above, according to the luggage antenna 10 of the present invention, the covered electric wire 12 is wound around the magnetic core 11 while leaving the lead-out portion 12c having a predetermined length on the winding start side 12a and the winding end side 12b. The lead-out part 12 c is bundled at a substantially central part 12 k in the longitudinal direction of the magnetic core 11. A connector 12e is provided at the terminal 12d of the bundled lead-out part 12c.

この構造によれば、コネクタ１２ｅに接続される制御装置が、ラゲージアンテナ１０における磁心１１の一方側１１ｃに近い位置及び他方側１１ｄに近い位置のいずれに設置される場合であっても、導出部１２ｃの端末１２ｄに設けられたコネクタ１２ｅを制御装置に好適に接続できる。 According to this structure, even if the control device connected to the connector 12e is installed at either the position near the one side 11c of the magnetic core 11 or the position near the other side 11d in the luggage antenna 10, the lead-out unit The connector 12e provided on the terminal 12d of 12c can be suitably connected to the control device.

その結果、コネクタ１２ｅに接続される制御装置の位置にかかわらずラゲージアンテナ１０を設置でき、ラゲージアンテナ１０の設置に係る汎用性を向上できる。 As a result, the luggage antenna 10 can be installed regardless of the position of the control device connected to the connector 12e, and the versatility related to the installation of the luggage antenna 10 can be improved.

また、本発明によれば、カバー１４がケース１３に嵌合される時に、被覆電線１２の導出部１２ｃは、ケース１３の通路１３ｂ内にて凹部１３ｃと凸部１４ｂとの間に挟みこまれることで、これら部位（凹部１３ｃ及び凸部１４ｂ）の形状に沿って折り曲げられる。この場合、被覆電線１２の導出部１２ｃのうち、ケース１３の通路１３ｂ内に配策される部分は、カバー１４が嵌合される前に比べて見かけ上長くなる。これにより、被覆電線１２の導出部１２ｃのうち、ケース１３の外部に露出する部分が短くなり、被覆電線１２の導出部１２ｃの配策構造が簡略化される。 Further, according to the present invention, when the cover 14 is fitted into the case 13, the lead-out portion 12 c of the covered wire 12 is sandwiched between the concave portion 13 c and the convex portion 14 b in the passage 13 b of the case 13. By this, it is bent along the shape of these parts (concave part 13c and convex part 14b). In this case, the portion of the lead-out portion 12c of the covered wire 12 that is routed in the passage 13b of the case 13 is apparently longer than before the cover 14 is fitted. Thereby, the part exposed to the exterior of the case 13 among the derivation | leading-out parts 12c of the covered electric wire 12 becomes short, and the routing structure of the derivation | leading-out part 12c of the covered electric wire 12 is simplified.

また、本発明によれば、磁心１１において、ボビン１１ｂに予め一体に設けられた係止部１１ｅ，１１ｆにより、被覆電線１２の巻き始め側１２ａ及び巻き終わり側１２ｂが、ボビン１１ｂに対して係止される。この場合、被覆電線１２の巻き始め側１２ａ及び巻き終わり側１２ｂをボビン１１ｂに対して固定するための部品が必要なく、ラゲージアンテナ１０における部品点数が低減される。 Further, according to the present invention, in the magnetic core 11, the winding start side 12a and the winding end side 12b of the covered electric wire 12 are engaged with the bobbin 11b by the locking portions 11e and 11f provided integrally with the bobbin 11b in advance. Stopped. In this case, parts for fixing the winding start side 12a and the winding end side 12b of the covered electric wire 12 to the bobbin 11b are not necessary, and the number of parts in the luggage antenna 10 is reduced.

また、本発明によれば、磁心１１において、ボビン１１ｂに予め一体に設けられた結束部１１ｇ，１１ｈにより、被覆電線１２の導出部１２ｃが束ねられる。この場合、被覆電線１２の導出部１２ｃを束ねるための部品が必要なく、ラゲージアンテナ１０における部品点数が低減される。 Further, according to the present invention, in the magnetic core 11, the lead-out portion 12c of the covered electric wire 12 is bundled by the bundling portions 11g and 11h provided in advance integrally with the bobbin 11b. In this case, a part for bundling the lead-out part 12c of the covered electric wire 12 is not necessary, and the number of parts in the luggage antenna 10 is reduced.

また、本発明によれば、被覆電線１２の巻き始め側１２ａ及び巻き終わり側１２ｂは、爪状の係止部１１ｅ，１１ｆに引っ掛けられることで、磁心１１のボビン１１ｂに対して係止される。この場合、被覆電線１２の巻き始め側１２ａ及び巻き終わり側１２ｂをボビン１１ｂに対して簡単に係止でき、ラゲージアンテナ１０の組み立て性が向上する。 Further, according to the present invention, the winding start side 12a and the winding end side 12b of the covered electric wire 12 are locked to the bobbin 11b of the magnetic core 11 by being hooked by the claw-shaped locking portions 11e and 11f. . In this case, the winding start side 12a and the winding end side 12b of the covered electric wire 12 can be easily locked to the bobbin 11b, and the assemblability of the luggage antenna 10 is improved.

また、本発明によれば、被覆電線１２の導出部１２ｃは、爪状の結束部１１ｇ，１１ｈに引っ掛けられることで束ねられる。この場合、被覆電線１２の導出部１２ｃを簡単に束ねることができ、ラゲージアンテナ１０の組み立て性が向上する。 Moreover, according to this invention, the derivation | leading-out part 12c of the covered electric wire 12 is bundled by being hooked on the claw-like binding parts 11g and 11h. In this case, the lead-out part 12c of the covered electric wire 12 can be easily bundled, and the assemblability of the luggage antenna 10 is improved.
